Question

ab6+3ab+b9a=1173 determinati a si b

Answer 1

ab6+3ab+b9a=1173
100a+10b+6+300+10a+b+100b+90+a=1173
111a+111b+396=1173|-396
111a+111b=777|:7
a+b=7
a=1,2,3,4,5,6
b=6,5,4,3,2,1

Answer 2

100a+10b+6+300+10a+b+100b+90+a=1173 111a+111b+396=1173 111x(a+b)=1173-396=777 a+b=7 1+6 2+5 3+4 4+3 5+2 6+1 a=1,2,3,4,5,6 B=1,2,3,4,5,6
